Abstract [en]

The goal of the Airspace operations and Safety Program (AOSP) at NASA is to develop new concepts and technologies for air traffic management that can be integrated within the National Airspace (NAS). A part of that effort consists of modeling the current and proposed ATM systems to understand challenges related to interoperability, impact on safety, workload on human operators, among other things. Necessary to any such modeling effort are abstractions of complex automated ground systems; wherein the abstractions represent the functional specifications of those systems. To that end, this paper presents an abstract functional model of the Terminal Sequencing and Spacing (TSS) system that provides automation to support in Terminal Radar Approach Control (TRACON) in sequencing and scheduling arriving airplanes at airports. TSS leverages the use of performance based navigation (PBN) procedures to y optimized profile descent (OPD) routes in order to minimize the need for vectoring in the form of course or altitude changes as well as decrease communications between pilots and controllers. The TSS model, in this work, employs simplified light dynamics under visual flight range (VFR) conditions to create a schedule for arriving flights that is free of conflict at all waypoints in the arrival routes including meter flxes, merge points, and runway thresholds. The utility of the TSS model is evaluated using scenarios that represent heavy traffic at the LaGuardia airport (LGA). Our initial validation effort shows that the TSS model implementation can create conflict free schedules for these traffic scenarios; we also integrate the TSS model with multi-agent system model of the LGA airspace.
